2Test application that uses plottools
3
4An application required by the REFL group and mainly test the Chisq class.
5   
6The following is a checklist of functionality to look for while testing:
71- Start the application:
8   the graph should have theory curve, experimental data, chisq
9   with a white background.
10
112- Hovering over any plotted data will highlight the whole data set
12   or line in yellow.
13
143- Left-clicking on the graph and dragging will drag the graph.
15
164- Using the mouse wheel will zoom in and out of the graph.
17
185- Right-clicking on the graph when no curve is highlighted will
19   pop up the context menu:
20   - 'Save image' will pop up a save dialog to save an image.
21   - 'Reset graph' will reset the graph to its original appearance after it
22                   has been dragged around or zoomed in or out.
23   - 'Change scale' will pop up a scale dialog with which the axes can
24                    be transformed. Each transformation choice should work.
